METALLIC-BELT PROTECTOR FOR VEHICLILTIRES.

Specification of Letters Patent. Application filed June 30, 1908. Serial No. 441,160.

. "atcnted Sept; 23, 1913.

One construction of metallic belt or pro-' tector designed to prerent skidding, slipping or puncturing of vehicle tires. with which I am familiar comprises a. iiiluralitv of interlocked cup-shaped links and rings, constituting a complete metallic tire armor. In this form of belt specially constructed links are used having cup shaped or raised .ceuters and a plurality of int ral retaining ti looped back and supporter l at their free ends by the raised. center. The main objection to this -l'orn'i of link is that the retaining; fingers which are relied upon to prevent slipping or skidding of the wheel are in contact with the road and receive all ofthe wear and consequci'itly soon wear down and break. Another objection resides in the fact that the loops through which the connecting rings are interlocked are liable to be bent through violent; contact with an obstruction thus binding the rings and destroying the flexibility of the belt. The cupshaped center forming the support for the finger ends also forms a repository for dirt which I have found collects and is retained .thercin.

My invention comprehends a new form of link having ring retaining fingers that; are entirely protected and are not subjected to any wear since they do not come in contact with the road-bed,'a support for the finger ends provided with a plurality of calks which contact with the road bed and 'eceive all of the wear, and which are capa le of withstanding the severe strain and shock they are subjected to, and an air space extending centrally through the link to permit the air to freelycirculate therethrough and keep the link from heatingand certain other modifications which will be more fully understood from the following detailed description.

' In the accompanying drawings in which I have illustrated practical embodiments of my invention like reference numerals indicate like parts throughout the several views.

Fi urel is a '1 i" n 4 i p an View o a section of belt comprising one form of my improved link.

Figs. l of further Fl; ll) lo 12 are structural details oi one Form of my link. Fig. 1. 3 a plan view of the preferaole -lorm at my improved link and Fig. lia sectional view thereof taken on line (""i h The belt or protector m-;')'|i-r.-; liul l and rings 2 interlocked a "owiato form a continuous metallic belt oi uilicicnt six-.- to encircle the outer periphery or tread oi a vehicle tire. The links 1 may he described as consisting ot a lipht but strong; metal stamping or bed plate hating retaining lingers er lUUI Xu' 1' formed integrally therewith and bent or looped back to rot-m a retainer for the rings 2 with which thcv are interlocked and a support 1 which may he a drop forging of toecalk or cold chilled steel provided with a plurality of radial dots 4- into which the ends of the retaiuiuf'f ling-1213s are bent, said slots forming upon the surface of the support a plurality of roughing calks or gripping surfaces. It will be apparent that when the fingers 1 are looped and the ends bent down into the slots twhich is. done after the connecting rings are three-led thereon, the support will be firmly held against any displacement by the retaining fingers.

The bed plate and supportinay be made in various different forms or shapes of which those illustrated in the drawing are Fig.1. II is a sectional view a few. In Figs. 1 to 3. I have shown a pertorated circular stamping or bed plate and a. cylindrical support having a projection 3 fitting into the perforation 4- (see Figs. 3 and 10). In Figs. l and 5 I have extended the slots 4 diametrically through the cylindrical support, forming two of the retaining fingers 1 longer than the other so that they will approximately meet at the center. This formhas the advantage of providing increased gripping power For the support. In Figs. 6 and 7 I form the bed plate and support hexagonal, and. in this torm of structure it will be noticed that the outer surfaces of the retaining fingers are' on the same plane with roughing calks of the support so that the wear will come upon both the retaining. fingers and the roughing calkS equally. In Figs. 8 and 9 the fingers are looped annularly and the support is grooved or cut out similarly so as to form an annular bearing for the connecting ring.

Referring to Figs. 13 and '14 in which I have shown my preferred structure, it will be noticed that I provide a large central air space or perforation 5 extending through the bed plate and support so that the air may circulate therethrough and keep the metal from unduly heating. This enlarged opening through the center of the link will not accumulate and retain dirt as the centrifugal force created by the running car will dislodge and throw it out should it be picked up or caught therein when in contact with the road-bed. Other advantages of providing this opening over the other forms of links shown are that the weight of link is materially reduced as well as securing an increment in the gripping power of the roughing calks. It will be further observed that in this form of link, that the looped 'good heat non-conducting material and is employed to keep the metal should it become excessively hot by reason'of continued use ona hot day from directly contacting with the rubber.

Having thus described my invention what I claim herein as new and desire to secure by Letters Patent is 1. An apertured link for a metallic'belt provided with a plurality of return bent loops and an apertured support for the free ends of said loops, said support extending above said ends. 0

2.- A link for a metallic belt having a plurality of retaining members, a su porting member supporting the free ends 0 said retaining ;members,' said. supporting member.

extending above the plane of the retaining I members.

3. A tire protector comprising perforated links and integral radially disposed loops, an apertured supporting member, supporting the ends of said loops, and links interlocked with said loops.

4. A tire protector having links provided with retaining members, a supporting member provided wlth radial slots, the free ends of said retaining members resting in said slots upon said supporting member and links interlocked with said retaining members.

5. A tire protector having links provided with retaining members, said retaining members having reduced ends, a slotted supporting member adapted to receive the 7. In a tread attachmentfor tire chains,

a plate provided with projecting Wearing members, a link having its outer face adapted to receive and support the plate and having its side edges bent upward and inward over the side edges of the plate so. as to form retaining lips therefor, said linkbeing also provided with a tongue bent to interlock with an adjacent link and having its end bent into contact with an edge of the plate.

8. In a tread attachment for tires, av crosschain having its center link formed with a relatively broad central portion having relatively narrow tongues extending therefrom bent to interlock with adjacent links and having its side edges bent upward and inward to form retaining lips, and a plate provided with projecting wearing members carried by the central portion of the link and secured thereto by the retaining lips.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses. I
